Device Authentication/Authorization Protocol for Home Network in Next Generation Security

摘要

In modern society, as the rapid development of IT technology combined with the computer-based high-speed communication networks makes it possible to provide a wide spectrum of services and devices, we have been confronting a new cultural transformation era, referred to as the information society. However, the requirements to be considered in security aspect have became more complicated and diversified, and there remains the same security vulnerability as in the preexisted media or protocol. Particularly, the smart home-network device is susceptible to the different kinds of attacks such as terminal hacking, virus attacks, and information leakage because the computing capacity is relatively low and the loading of already developed security functions is difficult. Although developed as one solution to this problem, PKI security authentication technology isn't suitable for multi-domain environments providing ubiquitous intelligent home-service, and so the development of a modified authentication system is urgent. Therefore, in this paper we proposed device authentication/authorization protocol using an ID-based public key. Our protocol provides to contribute to the development of the secured and efficient technology.
